CA18det vs SR20det(redtop)

Post by **Xero** » Sat Apr 12, 2003 10:27 am

^^I wouldn't suggest teh CA as an engine to get JUST because everyone is getting an SR, I don't think the CA should be bought for the sole purpose of originality.

the SR has oil squiters yes, the SR block is aluminum alloy, but still plenty strong,

I think there's a reason why the CA has a cult following in Japan and isn't the cool thing to use. most of it is because it's still in production, but I think it's the same reason why the AE86 is still being driven by some in Japan,

I like the CA because;

the block is iron(SRs have alloy blocks that are not as strong and need sleeves when power figures get past 400 or when more displacement is desired, Of course the CA can only really be punched up to the SR's stock size)

the valvetrain has less moving parts making it very stable(The SR's undercam rocker system is a step backward from the CA and requires "fixes" to make it stable)

it has a timing belt which stays accurate, chains stretch over time.(granted the SRs chain won't snap like a neglected belt will and destroy the valves and pistons)

CAs are for the most part ingnored these days due to their age and abundance of SRs so I don't have to fight many people for parts and prices are cheap(The SR though with it's abundance of aftermarket parts does offer more choices)

Xero, I'm getting some conflicting info on the intake manifold setup on the CA. I was under the impression that the JDM had the 8 port intake and the EDM had the 4 port intake. This is exactly opposite of what was stated in your link at the begining of this thread. Did I read this wrong, or am I mis-informed?

Post by **Nathan** » Sat Apr 12, 2003 10:27 am

the JDM does in fact have the 8 port intake with the butterflies to open the other set of runners...the european CA's have a 4 port from what I understand.

Post by **float_6969** » Sat Apr 12, 2003 10:27 am

Thats what I thought, but I've never seen either motor in real life, so I wanted to make sure I knew what was going on.

Here is a shot of the 8 port head. hope it helps a bit.

Post by **Xero** » Sat Apr 12, 2003 10:27 am

I learned that it's in fact the European head that has the 8 port head, w/ the butterflies, whereas the JDM one has the 4-port head, or it atleast doesn't have the butterflies,

Post by **Nathan** » Sat Apr 12, 2003 10:27 am

hmmm, perhaps I'm wrong! Can anyone verify? well I will know soon enough...

Post by **drumma022** » Sat Apr 12, 2003 10:27 am

i can verify that 2 CA's came in from japan... (japanese packaging and all) both came with the 8 port and butterflies too. I also know that other variations included a different Cam Cover like what Paul had.

Post by **Nathan** » Sat Apr 12, 2003 10:27 am

Hmmm, thats what I thought too, and Brian said he'd taken the butterflies out which told me it was an 8 port...besides, nobody ever imports the european engines.

Post by **themadscientist** » Sat Apr 12, 2003 10:27 am

I can verify that my wife's 180sx parked outside has the eight port as well. the four port is Europe.

Post by **drumma022** » Sat Apr 12, 2003 10:27 am

Im positive that the butterflies are out on that motor, cause they are out on mine too. I could prolly tell you more about the motor than he can, cause i helped build it with Rock...

Post by **Nathan** » Sat Apr 12, 2003 10:27 am

well then why dont you answer the im I just sent you

Post by **Xero** » Sat Apr 12, 2003 10:27 am

The only thing that pic helped me do was blow my wad! Jeez, I really wish Daunt could get those motors faster!

Post by **nlzmo400r** » Sat Apr 12, 2003 10:27 am

yea ,that was a cool shot, wish i had one in my garage

Post by **themadscientist** » Sat Apr 12, 2003 10:27 am

I wish I had some race queens in my garage:naughty

Post by **nlzmo400r** » Sat Apr 12, 2003 10:27 am

haha, every engine should come with one IMO, u want an RB26DETT??, we'll throw in two just for good measure

Post by **themadscientist** » Sat Apr 12, 2003 10:27 am

has anyone thought of taking a set of either SRs or CAs and grafting them into a 4.0 or 3.6 liter straight 8? Is it just me? is it the medication? are the smurfs really after me for my DNA? just some questions bouncing around in my head while I wait for the coffee to kick in.

Post by **Xero** » Sat Apr 12, 2003 10:27 am

^^no, it's you pulling ahead of me in the Mad Scientist of NICO race

DAMN!! I need to get my brain juices goin'

Post by **float_6969** » Sat Apr 12, 2003 10:27 am

TMS-1, Xero-0(hehehe) Sorry Xero, DNA hungry smurfs is hard to beat.

Post by **nlzmo400r** » Sat Apr 12, 2003 10:27 am

each of yall have one HELL of an imagination, how do yall come up with this crap, and as to an answer, ive thought about it, butnever really looked into it as a possibilty, where thers $$ theres a way

Quote »are the smurfs really after me for my DNA?[/quote] Hmmm, have you seen them or did you sense some conspiring on ALJAZEERA:D My observation of the SR's is a motor that when something goes wrong, it doesn't stop (ie blowing a headgasket or a piston). Lean out the SR and you can (most of the time) kiss that shiny block goodbye. Lean out the CA, clean up the cylinders(s) with a light hone, put in used piston and a new headgasket and rod bolts and keep going. The only SR powered 240 I've seen on my end that seems to be holding up pretty well is the one I recently did for one of my friends and the only reason I did it for him is because he used the fuel management that I chose and that's an SDS. Did a 240 with CA18DET and sold him an SDS efi+installed it and I haven't seen or heard from the guy since he drove away with the car (another satsified customer). The Sr's I've seen with JWT stuff or the infamous haltech seems to be the drama queens, but that's just what I see in my neck of the woods where SR powered vehicles are in abundance mainly FWD which are all garbage. You wanna have some worry-fun where you can rev the engine silly and can drive around day in 3rd gear, then the CA's the way to go. But if you want to just have someone throw something in and get some good street power and some good low grunt, then I would say spend your money on the KA24DE(T). But if you must have what Johnny Tran wanted for his civics so he could have the edge at racewars, then the famous SR20 is the way to go. Good luck chosing and happy boosting:help This picture might be the ruff product of a CA18DET/240/SDS install, but this customer was so pleased with his car's performance, he has not come by to let me fine tune his car and dyno it. I just love it when this happens! And as for the SR guys, well, I've seen alot of disappointed faces.

Post by **drumma022** » Sat Apr 12, 2003 10:27 am

Boost boy... where have you been all this time. I have had the CA in my s14 with SDS for about 2 years now and still running a rough tuning map. Just thought id point that out.

well, my underpants gnomes just wispered to me, "doode, GTiR AWD SR20" but I think that's blasphemy, so I say GTiR AWD CA18

now that I think about that, I think that'd be sick,

Post by **themadscientist** » Sat Apr 12, 2003 10:27 am

some U12 Bluebirds came with a CA18DET AWD.

Post by **Xero** » Sat Apr 12, 2003 10:27 am

^^does this mean I get a point and it's all tied up? =)

and I think it was the bluebird I was thinking of, not the GTiR,

but the question is, could it fit? the S13 engine bay looks pretty unforgiving, I wonder if you could use the R32 GTR front suspension since it's prepped for AWD, hmmmm...

Post by **themadscientist** » Sat Apr 12, 2003 10:27 am

no but here's your late pass, I compiled a list of body and suspension parts required to get it done two years ago.

I'll give you a point if you can go through a McDonald's drive through without having to fill up your gas tank by the time you are done! "fast food", yeah right!

Post by **Xero** » Sat Apr 12, 2003 10:27 am

lol!!! DAMN!! arggg...I am truly running against a master, aren't I

I'll come up with something for you tomorrow, I'll think really hard, does it HAVE to be Nissan related? eh?

and boy do I love thread jacking

isn't McDonalds called something else over there?
